The worlds first atomic explosion, New Mexico, at the Alamogordo Test Range, test name Trinity . Intended to prove the new implosion design developed at Los Alamos during the previous year, an early morning thunderstorm delayed the test from its originally scheduled time of 4 a.m. until nearly 5:30 a.m. The "gadget" was an untested implosion device using a plutonium later weaponized becoming the "Fatman" bomb dropped on Hiroshima. The origin of the name Trinity is thought to have been provided by Oppenheimer with reference to the divine Hindu trinity of Brahma, Vishnu and Shiva. Following the Trinity test he is reported to have recited the Bhagavad-Gita, "If the radiance of a thousand suns Were to burst at once into the sky, That would be like the splendour of the Mighty One..I am become Death, The shatterer of Worlds". This clip is a sequence of Rapatronic images showing the first 109 millionths of second after detonation.
